Pall MicroFunnel Plus Filter Funnel w/ Metricel Black Membrane, 0.45um, 100mL, 47mm, Gridded - 50/Pk - 4808

Pall Corporation engineers proprietary membrane media for the membrane filter technique, purpose-built for microbial recovery and analytical clarification at the laboratory bench. A filter funnel draws an entire liquid sample through a seated membrane disc, gathering everything the membrane retains onto one surface for analysis. The hydrophilic PES surface draws aqueous samples through readily while sustaining fast throughput on large aqueous volumes and holds adsorption low to protect captured cells and analytes. Reproducible recovery of the retained organisms and particulates follows, ready for colony counting, gravimetric weighing, or instrumental analysis.

Key Characteristics

• Hydrophilic surface wets aqueous samples without pre-wetting
• Uniform rated pore gives consistent surface retention across the membrane
• High-flux polyethersulfone speeds filtration of large water and beverage samples
• Low extractables keep the filtrate clean for downstream analysis
• Low protein binding preserves captured organisms and analytes for recovery

Dependable contamination monitoring protects the water and beverage lots you clear for release. A reproducible membrane seat and a leak-free sample path keep your enumeration results defensible under the standardized membrane filter methods you report against.

Hydrophilic

• Sterility Sample Prep - Hydrophilic PES filters culture media and buffers for membrane-based microbial testing workflows.
• Large-Volume Water QC - Polyethersulfone sustains fast flow to filter large potable-water samples for microbial monitoring.
• Legionella Recovery - High-flux PES membranes recover Legionella from large water volumes with low background interference.
• Low-Binding Recovery - The low-protein-binding surface preserves captured organisms and analytes for accurate enumeration.
• Environmental Monitoring - Fast-flow polyethersulfone recovers indicator organisms from environmental water samples readily.
• Beverage Screening - PES membranes clear large beverage volumes quickly, concentrating spoilage organisms for plate counts.
